A few of us around Victoria grow this Agave. None of use know which one it is. It is definitely a dwarf, the largest one I've seen may be as large as a 4" pot. Hard to say, because there is never just one. It throw pups, like you wouldn't believe. I picked up a 2" potted one earlier this year, in which I harvested 6 off-set. Three I was able to root and sell this year in 2" pots. I have three more coming along slowly. Two are still very tiny, they both share the same plug. The one in the picture I got at a different time. I'm just looking for guesses and ideas. Just give me some names to narrow it down. One photo was with a flash, the other two from near by grow lights. I would call the colour a blue-grey with slight touch of green.
